Title: Production of reinforced synthetic resin pipes
IPC: F16L9/128
Filed: 1970-12-29
Abstract: 1333567 Reinforced synthetic resin pipe MITSUBISHI PETROCHEMICAL CO Ltd 29 Dec 1970 [27 Dec 1969] 61421/70 Heading B5A [Also in Division F2] A reinforced synthetic resin pipe is formed by inserting a reinforcing frame 1a (Fig. 3B) into a mould 2a, and rotating the mould 2a while inserting and heating powdered synthetic resin, the speed of mould rotation being such that the reinforcing frame 1a becomes embedded in melted resin and is coaxial with the finished pipe (see Fig. 3D). The frame diameter l may equal the inner or outer diameter of the pipe a. An example is described using high density polyethylene having a melt index of 6 and a specific gravity of 0À950. An iron mould 2a is employed, closed at each end by centrally apertured iron discs (2b) (see Fig. 2, not reproduced) heated by burners. The reinforcing frame 1 (Fig. 4) comprises iron, steel, aluminium, copper or reinforced plastics. The mould 2a is rotated at 25 r.p.m. to give a rising angle of raw material of about 135 degrees (see Fig. 3B), and the mould 2a is cooled before removing the formed pipe.

Filed: 1968-12-30
Abstract: 1287570 Extracting coal COAL INDUSTRY (PATENTS) Ltd 30 Dec 1969 [30 Dec 1968] 61651/68 Heading C5E A coal extract or solution is made by dissolving the coal at between 360‹ and 425‹ C. in an organic solvent, e.g. coal tar oil, to which has been added a cyclic activator, preferably nitrogenous. Solvent is recovered and recycled to the extraction step. The activator comprises either a compound having at least two carbocyclic rings or a heterocyclic ring having nitrogen as the heteroatom and which is capable of dehydrogenation which gives rise to an aromatic ring without rearrangement, or a compound having nitrogen in an aromatic ring. The activator preferably forms 3% to 5% b.w. of the solvent, which may range from 2 to 5 times the weight of the coal. Activators mentioned include 1,2,3,4-tetrahydroquinoline, indoline, indole, pyrrolidine, pyrazine, piperidine, and may be nitrogen-free, e.g. perhydrophenanthrene or 9,10-dihydroanthracene. Hydrogenated tar bases may be used. The activator may be added to used solvent, which may be topped up and recycled.

Title: Impression-surfaced conveyor belting and method of manufacture
IPC: B29D29/06
Filed: 1978-08-03
Abstract: The disclosure is of impression surface conveyor belting and a method for its manufacture. The belting comprises a plurality of substantially parallel textile yarns of a specific character, integrated (in a unitary structure) with a layer of consolidated staple fibers and encapsulated in a matrix of flexible elastomer or resin. Included in the integral structure is an impression wear surface of partially isolated matrix material containing a portion of the consolidated staple fibers (a fiber bundle) which are continuously anchored in a portion of the non-isolated belting matrix. The belting of the invention is useful to manufacture non-laminated, impression surface, conveyor belts which exhibit advantageous properties of wear resistance, stability in running and structural integrity.

Title: Method and apparatus for automatically inserting electrical connectors into housings
IPC: H01R43/20
Filed: 1978-09-01
Abstract: In a system for crimping connectors 3 on to electrical conductors 9 and inserting the crimped connectors into socket openings in a housing 53, the connectors are not severed from the carrier strip 4 on which they are originally supplied until they have been gripped by a gripper device 13 which is to insert them into their respective socket openings.

Patent GB-2004014-A (GB)
Title: Improvements in fluid-pressure operated boosters
IPC: B60T13/573
Filed: 1978-09-11
Abstract: A fluid-pressure operated booster is described of the kind which employs a conically deformable reaction disc 7 with angularly spaced ribs 11 to support the booster diaphragm and to provide a reaction or "feel" to the brake operator. The invention aims to increase the boost ratio of such a booster at low input forces to overcome the static seal friction of sliding parts of the booster and of a master cylinder connected to it. This is done by providing selective connections at different radii between a valve operating member in 28 and the reaction disc 7. The selective connections are made by two co-axial annular plates 18, 19 the smaller one 18 being operative for low input forces but resiliently deformable and therefore ineffective at higher input forces when the plate 19 reacts directly through legs 12 on the member 28. <IMAGE>

Title: Automatic drain valve
IPC: F16T1/00
Filed: 1978-10-04
Abstract: An auto drain valve for use in a pressure vessel has a differential area piston (8) with its stop surface (8B) and stem (8A) directed downwardly and carries a liquid outlet valve member (10) at the lower end of its stem.

Patent GB-2012870-A (GB)
Title: Multi-stage Rotary Pumps
IPC: F04D13/12
Filed: 1979-01-11
Abstract: A jet pump 5 provided at the fluid input 13 to one of the stages is supplied with fluid from the output 9 of said one stage or a stage downstream from said one stage. The driving fluid exiting from the jet pump nozzle entrains the lower pressure fluid supplied to said one stage whereby the static pressure of the fluid supply to said one stage is increased. In this way a higher pressure head may be obtained compared with a conventional multi- stage pump of similar dimensions operating at a similar rotational speed. Each stage may be of centrifugal regenerative, sliding-vane, gear or roller-vane type. The stages may be connected in series or parallel and a jet pump may be provided at the inlet to each stage. An intermediate take-off outlet 7 may be provided between two successive stages. <IMAGE>

IPC: H04R25/04
Abstract: 790,468. Sets for deaf persons. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 3, 1956 [Oct. 6, 1955], No. 30129/56. Class 40 (4). In a pocket hearing-aid consisting of a flat box containing a microphone, amplifier, and battery, the microphone is suspended resiliently in a space insulated in a sound-proof manner from the rest of the box and communicating with the atmosphere through at least one opening in the wall of the box, and the resonant frequency of the microphone space together with its opening(s) lies above the pass-band of the apparatus. As shown, the hearing-aid has a frame 1 of synthetic resin and the conventional ports including a number of transistors 3, a microphone 5, a volume control 7 and a battery 9 are housed in a compartment at its back. A front cover 11 and a back cover (not shown) are provided, one or more earphones (not shown) being connected by inserting their plugs into sockets 13 in the upper edge of frame 1. The microphone 5, provided at the front with a circular opening 15, is secured by three foamed rubber suspension elements 17 in a metal ring 19 having two contacts 21. Contact springs 23, secured to the frame 1, co-act with these contacts and also serve to press the ring 19 against a curved rim 25 formed on the frame 1. The free front edge of rim 25 carries a rubber strip 27 of H-shaped section which engages the inner side of the cover 11 to form a sound-tight closure of the microphone space bounded by the rim 25. The resonant frequency of this space together with the opening 29 thereof is chosen to lie above the pass-band of the apparatus, thus reducing " clothes noise " when the hearing-aid is in use.
